The z2ram is a very simple driver, used to configure (slower) Zorro II RAM as
a swap device.  So I'm not so surprised no one submitted functional patches.

I believe it's still being used.
Probably it could be modified to use mtdram.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
